This invention relatesto new and useful improvements in saw uards.

One of -the objects of provision of a new a and improved type of sawguard adapted to be applied tosjal s of the floating type of guardwherein the work can be readily passed beneath the guard which willposition itself relative the work so that the guard will at alltimesprotecttheoperator fromthe-movingsaw teeth.

"A further object of the invention is the provision of a saw guard ofthe above type which; is extremely vsimple in construction, and can bemanufactured at a very'low cost and can be quickly and readily appliedto movable arbor saws at a very low cost.

lVith the above and other objects in view, the invention consists in thenovel features of construction, the combination and arrangement of partshereinafter more fully set forth pointed out in the claims and shown'inthe accompanying drawings wherein: r

formedwithinside walls of asubstanti- 7 ally rectangular box-like guardmember 16.

The'guard member 16 may be formed of sheet metal or other suitablematerial and is vslotted longitudinally at one siderto permit thepassage of the saw therethrough, while the opposite side is also slottedat 17 to permit movement of arm 12 with respect to the guard, as shownin Figure 4, while one end of the slot 17 is enlarged at 18 to permitmovement therein of the hand lever 13.

The guard member 16 is formed with an inclined face 19 at one end forengaging the work, as shown in Figure 4, so that the said guard memberwill readily ride over the work, while the saw blade 4'is being passedthrough the work, this being clearly illustrated in Figure 5, and due tothe fact, that the guard member 16 is loosely mounted upon the rotatablesurface 20 onthe ends of pin 14, the guard member may readily assumevarious positions with respect to the work as the saw passes through thework. The pin 14: is carried by arm 12 adjacent the outer end thereofand in addition to the rotatable sleeves 20, the eX- tremities of thepin are reduced and fitted within the transverse slots 15,as shown inFigure 7. I

Referring particularly to the perspectiv view in Figure 8 of thedrawings, the guard member 16 is providedupon its upper face with aglass window 18. The function of this window is for observing the cutand work through the box when the saw is utilized' as a rip saw, inwhich event the rip Wisconsin.

A device of the class described includ ing a movable arm,'a movablesaw member carried thereby, an arcuate arm connected tothe movable armand aligned with the saw," a hand lever carried by the second arm and amovable guardm'ember positioned over the saw and having connection withthe arcuate arm whereby the movement of the arcuate arm will cause theguard member to assume various relative positions with respect to thesaw.

In testimony that I claim the foregoing I have hereunto set In hand atWauwatosa, in the county of Milwaukee and State of FREDERICK o. KUMMER.

It will be apparent from the foregoing I that I have provided a verysimple and inexpensive saw guard which'can be readily attached to amovable saw arbor and so arranged that the guard will at all times bepositioned over the saw blade so as to positively protect the operatorregardless of the position of the work with respect to the saw and theguard will be moved simulthe appended claims.
